IMPROVEMENT IN DEVICE FOR TRANSMITTING ROTARY MOTION.

TO ALL WHOM IT MAY CONCERN:

Beit known that I, L. FLANDERS, of Philadelphia, Pennsylvania, 'have invented an. Adjustable Device for Transmitting Rotary Motion; and I do hereby declare the following to bca full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked Ithereon.

My `invention consists of' a device, fully described hereafter, by which a rotary motion may be transmitted from one shaft; to another, nq matter what the relative position of the two Shafts may be, the device being such that the shaftto be driven is net subjectcd to any lateral strain.

In'order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation. On reference to the accompanying drawing, which forms a part of this 'spcciiicationft Figure 1 is a front view ofmy device for transmitting motion.

Figure 2 an end view,

Figure 3 asectional view on the line 14?, fig. 1,

Figure 4 a section on the line 3-4, iig. 3, and

Figure 5 a detached sectional view of part of the device, drawn to an enlarged scale.

'Similar lettersrrefer to similar parts throughout the several views The frame of the device consists of the two arms b and b', "connected together at their opposite ends, the

4M,frame bein'gdivided longitudinally into two parts, secured together at points aV by suitable bolts. Passing through the arm b of the frame, and lturning in the same, is a. shaft, B, a similar shaft, C, turning in the opposite arm bv of the frame. Onoue vend of the shaftB is a bevel-wheel, c, which revolves in an opening, d, formed inA one,end of the frame, and gearing into this wheel c is a similar bevel-wheel, e, turning upon the shaft C. Upon the opposite end of `this shaft is a wornnf, and a similar worm f is formed on or secured to the end of the shaft C. Between thev diverging ends of the shafts B, and C, and gearing into the worms f and f', is a worm-wheel, I), thetubular hubs h h of-which turn in the frame.A The shaft C projects-through and turns in the tubular piece t' of the frame A, andfterminate's in a bevel-wheel, j. Afratne, E, is arranged to turn freely on the tubular projection i of the frame A, and may be secured to the same in any desired position by means of set-screws 7c k, (iig 5,) and' in this frame E turns a shaft, F', provided with a pulley, m, and a bevel-wheel, Z, gearing into the wheelj of the shaft C. Let4 us suppose the shaft X to be .a-`boringbar, to which it is necessary to impart a rotary `motion from someadjacent line of shafting. The tlibular hub of the worm-wheel D is adjusted to thc boring-bar in any desirable manner, and secured thereto, after which the frame A can be turned upon the bar X as a centre to any desired position, and secured by suitable appliances after adjustment, after which the frame E is turned on the'tubular projection 1l of the frame to such a point that its pulley m shall be in a proper position for receiving the driving-belt, by which a rotary motion is imparted to the shaft F, and thence through the wheels Z and j, e' and c, shafts B andfC, and' worms ff,l to the worm-wheel D and boring-bar X.'

Although I have alluded to the ldevice as being used inconnection with a boring-bar, it may be employed in transmitting motion in other cases where a complex system of gearing or driving-belts has been heretofore used.

An importantfeature in my invention is;v the application of power to opposite 0r nearly opposite edges of the wheel-D--an arrangement which must relieve the shaft or bar X from all lateral strain.

I do not desire to confine myself to the precise form or construction of the frame A, as the same may bc modified without departing from the main features of ny invention; butI claim as my invention, and desire to secure by Letters Patent- The shafts B and @,geared together, and cach furnished aworm,f, gearing into awheel D, in combination with an adjustable frame E, shaft F, and bevel-wheel Z, gearing into a bevcl-whcel on the shaft C, the whole being constructed and operating substantially as described.

In testimony whereof I have signed my name to this speelnca-tion in the presence of two subscribing witnesses.

L. B. FLANDERS.
